' use rrnn sms WAL'IHER HELLMUIH GREIFENHAGEN, MUNICH, GERMANY. i

To @ZZ whom, it may concern: Be it known that I, WALTHER HELLMUTH ,GREIFENHAGEM a rsub'ect of the King of Bainjection is involved. For this purpose it is desirable to provide for lthe purpose indicated a .cheap device which can Without involving considerable eX ense be destroyed after being once used? vSeveral devices which have been designed with this object in view are for various reasons ineflicient in their action. In some cases the means for fastening the receptacle are not suiiiciently secure to prevent premature evaporation of the antise tic or medicinal substance contained in t esaid rece tacle. Infother cases,

more particularly int ose inyvhich collapsible tubes are used, the rece tacle is not ada ted to contain a liquid an can only be for viscous substances The known cups or flasks with narrow orifices normally closed by means of a soft substance-such as wax, gelatin, or the like-have the disadvantage that portions of the-said substance are liable to become mixed with the liquid in the receptacle or that even'the entire plug or stopper may be dissolved or decomposedby the said liquid.

The object of the present invention is to provide a device for. introducing drops of antiseptic or medicinal liquid into small cavities of the human body Without involving any of the disadvantages hereinbefore indicated.-

The invention is illustrated in the annexed drawings, in which,-

Figure 1 is an elevation of the device, 'and i Fig. 2 a view illustratingl the manner 1n which the latter is used.

DROP-MASK'.

Patented .13.11.22, 190:?.

` The device comprises aglass tube @,of suitable length and diameter, hermetically closed at both endslbymeans of plugs c and d, of cork or other suitable material. The lower orifice of the said tube isconsiderably smaller than the upper orice,so that it can be 'conveniently introduced into small cavities-for instance, into the penis'. The `esi sential novel feature of, the device consists, however, in the constriction b between the orifices of the tube a, which'produces a narrow duct or assage at the central part of the said tube, the diameter of the duct or passage beingvsuch that only a orftion of the contents of the tube can flow 'rom the latter through the smaller orice,eve'n' when both orifices are open; This arrangement not only allows of easily obtaining the discharge of the liquid in the form' of drops, but also facilitates the closing of the discharge-orifice.

For use the plui moved from the Vscharge-orifice4 and the orstopper c is first re-` em ty portion of the tube between the said or" ce and the constriction b is'thereupon introduced into the part to be treated. Thereu on the u er lug or sto er d is removed as shown ifi'rlligi, and th) liquid is thus en abled to flow in the form of dro s into the said part'. The cost of the `sma tube and its contents is so small that practically no material loss is involved by destroying it immediately after use.

What I claim as my invention, and desire to secure by`Letters Patent of the United States, is'- i A medicinaldrop-ilaskhaving a large ori- Y fice at one end and a small orifice at the other end and-a constricted passage-way intermediate of its ends adapted to permit assage of liquid dro by drop only, the bo y of the ilask toward t e smaller end being tapered to the small orifice at the end thereof for the' purpose described.l p

In witness whereof I have signed this specification in the presence of two witnesses.
